Airship



Sept. 2, 1930. J. M. BOSCARDIN AIRSHIP Filed Aug. 8, 1929 Patented Sept. 2, 1930 UNITED STATES JOHN M. BOSCARDIN, OF CANAAN, CONNECTICUT Amsiiir Application filed August 8,1929. Serial No. 384,254.

This invention relates to airships and more particularly to the type employing a gas bag as well as a motor.

The principal object is to utilize the draft a from the propeller blades to revolve a conical cylinder having spiral blades thereon and containing a lighter than air gas.

Heretofore, the draft from the propeller blades has never been utilized in the propelio ling of the craft, and where a helical cylinder has been utilized, it has always been i driven by a powersha-ft from the power unit. It is my intention to have the cylinder, which is'filled with lighter than air gas, and has 15 spiral blades on the outside in the form of a helix, to be revolved by the draft created by the revolving propeller blades and at the same time to be able to connect up the cylindrical cylinder with the power unit by the 2: means of a clutch when it is necessary.

Another object is to provide an airship with a compartment filled with lighter than air gas that may be revolved by the draft from the propeller blades or from the power that rotates the propeller.

Other objects will be disclosed in the speci 'fication and drawings forming apart of this application.

In the drawings: I1 Figure'l is a top plan view of the airship;

Figure 2 is a side elevation partly in section; and

Figure 3is a detailed view in sect-ion of the clutch mechanism. 1 Referring to the drawings, in which like parts are designated by similar numerals: Numerall designates a frame having cross cuts 2, wings 3 and a rudder 1. Within the frame 1 is mounted a cylinder 5 on a shaft 6. The shaft 6 has supports 7 and rests in bearings 8 at each end. Along the sides of the frame 1 are roller bearings 9 in which the cylinder 5 may revolve. Around the outside of the cylinder 5 are spiral blades 10. On the opposite end from the rudder 4 is the usual motor 11 and propeller 12. Between the motor 11 and the shaft 6 is a clutch 13 for throwing the shaft 6 into and out of engagement with the motor 11. A rod 14 leads from the clutch '13 to the control c-ompart ment 15 where the clutch may be operated by lever 16. v The passenger compartment 17 is adjacent the control compartment 15 at the opposite end from the motor 11.

A door 18 leads into the passenger and control compartments 17 and 15, respectively. In the Wings 3 is positioned a gas tank 19 to furnish fuel to the motor 11. About the rudder l are placed wings 20. The cylinder 5 Will be filled With a gas lighter than air through opening 21.

As actually operated, the motor 11 will be started in the usual manner. Due to the gas filled cylinder 5 the airship will be unusually buoyant and much less dificulty will be experienced in taking off. As the propeller 12 revolves, a draft will be directed backward directly along the cylinder 5 and against the spiral blades 10. This will cause the cylinder 5 to revolve and greatly facili-' tate the movement of the craft. Since the cylinder 5 is mounted in roller bearings 9 and the shaft 6 in bearings 8, very little resistance will be ofiered to the revolving of the cylinder 5. Should it be deemed necessary to facilitate the revolving of the cylinder 5, the clutch 13, mounted between the motor 11 and the shaft 6, may be thrown into engagement with the shaft 6 by means of control lever 16, thus having the cylinder motor driven as well as propelled by the draft from the propeller 12'.

Dueto the particular buoyancy of the craft, large passenger space is provided at the rear. Further, due to the gas filled chamber the wing spread may be materially cut down and a much safer airship provided.

Having described my invention, what I claim as new and novel is:

1. An airship comprising a frame, a cylindrical gas chamber rotatably mounted in said frame, blades mounted on said gas chamber, means in the form of a propeller for revolving said gas chamber.

2. An airship comprising a frame, a cy lindrical gas chamber rotatably mounted in said frame, spiral blades mounted on said gas chamber, means in the form of a propeller for revolving said gas chamber.

3. An airship comprising a frame, a cy lindrical gas chamber rotatably mounted in said frame, spiral blades mounted on said gas chamber, a propeller, means for revolving said propeller, the revolving propeller ir'eating air currents to rotate said gas cham- 4. An airship comprising a frame, a cylvcinder mounted in said frame, blades mounted on said cylinder, means in the form of a.

propeller for revolving said cylinder.

5. An airship comprising a frame, a cylinder mounted in said frame, spiral blades mounted on said cylinder, means in the form of a propeller for revolving said cylinder.

6. An airship comprising a frame, a'cylinder rotatably mounted in said frame, blades mounted on said cylinder, means in the form of a propeller for revolving said cylinder, means for revolving said propeller, and other means for connecting and disconnecting said cylinder to and from said means for rotating said propeller.

7. An air hip-comprisinga frame, a cy- I lindrical gas'chamber rotatably meunted in said frame, blades mounted on said gas chanr ber, means in the form of a propeller for re volving said gas chamber, means for mew-- ing said propeller, and other means for connecting and disconnecting said gas chamber to andfrom said means for rotating saidpropeller, r w i 8. An airship comprising a frame, a cylindrical gaschamber rotatablymounted in said frame, spiral'blades mountedon said gas chamber, means in the form of a propeller for revolving said gas chamber, means for revolving said propeller, and other means for connecting and disconnecting said gas chamber to and from said means for rotating said 40 propeller.

9. An airship comprisinga frame, a shaft rotatably mounted in said frame, a cylindrical gas filled cylinder mounted on saidshaft, roller bearings on said frame to support said 765 cylinder, spiral bladesron the outside of said cylinder, a propeller at one end of said cylinder, a motor for revolving said propeller, the revolving of said propeller causing air currents to strike said spiral blades and revolve said cylinder, a clutch supported by said frame and disposed between said motor and said shaft for throwing said shaft into and out of engagement'with'said motor.
